I’ve been working on a free language learning app that uses a local AI model to translate words and sentences. You can read sentences, short stories, or watch YouTube videos with translatable captions. It mostly follows the principles of the comprehensible input theory. Think of it like LingQ, but free and with any language combination.

The main goal is for the app to run entirely on the client side and stay completely free.

Personally, I can’t stand Anki or Duolingo—I’d rather read actual sentences that are fine-tuned to my level.

This plugin (Language Reactor) works with YouTube as well, you should try it. + Target and native captions in parallel. + Translate any word on hover (more on click). + Hotkeys to repeat, move to previous/next segment. + Pronounce single word. - Moderate downside that it's not possible to select and translate multiple words. I hardly use LingQ with this plugin, it's more immersive and much allows you focus on listening even more (which is good).
